LAMP-SHADE.

Specification of Letters Eatent.

Patented Aug. 29, T9116.

Application filed February 16, 1916. Serial No. 78,636.

To all whom it may concern:

Be it known that 1 Ronnn'r L. CLARK, a citizen of the United States, and a resident of Union, in the county of Monroe and State of West Virginia, have invented a new and Improved Lamp-Shade, of'which the following is a full, clear, and exact description.

My invention, relates to a shade particularly. intended for use on incandescent lamps and has for an object to provide a shade that may be readily applied to a lamp or removed therefrom, and so arranged as to be readily manipulated to shade the lamp or to expose the same.

The purposes of my invention are attained by a construction involving a novel arrangement of a drop curtain to be raised in collapsed form or tobe lowered to a shading position through the medium of a novel arrangement of draw string.

The purposes and advantages of my'improved shade will appear more fully from the specific description following.

Reference is to be had to the accompanying drawings forming a part of this specification in which similar reference characters indicate corresponding parts in all the views.

Figure 1 is a vertical section of a lamp shade formed in accordance with my invention, showing the same applied to an incandescent lamp; Fig. 2 is a sectional view showing the shade detached and collapsed; Fig. 3 is a view similar to Fig. 2 but showing a slightly different form of the invention.

In carrying out the invention, in the form shown in Figs. 1 and 2, a supporting head 10 is provided of disk-like form having a central opening 11 adapted to receive the threaded neck a of an incandescent lamp A and permit the said neck to protrude through the head for engagement with the usual lamp socket (not shown). The head 10 may have any suitable means for fastening it to the neck a there being shown for the purpose, a spindle or screw 13, extending radially in the said head and formed with a knurled knob, said spindle beingadapted to bear against said neck a. Se-- cured to the head 10 and depending from the same at the under side is a drop curtain 12 of truncated cone shape or otherwise tapering toward the upper end. The curtain is of a length so that when dropped, the

lower edge thereof will be sufliciently below the lamp A to shade the latter. The curtain 12 is provided with'a series of annular bands 14:, about which the material of the curtain is turned as at 15 and sewed or otherwise secured to retain the bands in pos1t1on. The bands 14 are applied at spaced lntervals on the curtain 12 and are of grad ually decreasing diameter from the lowermost band upwardly so that the bands will nest one within another when the curtain is ralsed and collapsed against the under side of the head 10. The lower end of the curta n carries a ring 16 and connected with said ring is a draw string 17 to raise and lower the curtain. Said string 17 is connected with the ring 16 at diametrically 0pp os1te sides-of the curtain 12 and is carrled upwardly over the head 10 and downwardly through apertures 18 in said head, the central portion of the string hanging in looped form within the shade, the looped portion of the string being of a length to extend below the ring 16 ,for convenient grasping of said loop. It will be seen that a downward pull on the loop 19 of the draw string 17 will carry the ring 16 upwardly and collapse the shade 12, the annular bands 14 being successively nested as the curtain rises until the ring 16 reaches a position close to the head 10, as illustrated in Fig. 2.

The frictional engagement of the draw string with the head 10is sufiicient to. maintain the curtain in collapsed position but the frictional engagement will readily yield to a slight downward pull on the ring 16 to drop the curtain over the lamp.

In Fig. 3 the shade is very similar to that shown in Figs. 1 and 2, thedifference being the form'of the bands applied to the curtain.- Tn the form shown in Fig. 3, a series of flat bands 14 are applied to the curtain 12' instead of bands round in cross section as at 14;. In addition to the series of bands 14, a band 14: is in fixed relation to the lower ring 16* of the curtain 12 and a flat band or collar 14 depends from the disk-like head 10 at the under side of the latter. The head 10 is formed with a central opening 11 to receive the lamp neck and with a spindle or set screw 13 as in the first described construction. Also, the draw string 17 is similarly connected at its ends with the bottom ring 16 and extends upwardly over the head l0 and downwardly through i a the openings 18 -therein, and is formed with afi intermediate loop -19. asin the first con- 7 struction;

Having thus described my invention I claim as new and desire to secure by Letters Patent:

1. A lamp shade of the class described including a head having an opening to fit over a lamp, a collapsible drop curtain depending from the said head and flaring toward its lower end,- a series of annular bands on the curtain of successively increasing diameter toward the lower end of the curtain to nest one within. another, a ring carried by'the curtain at the lower edge thereof, and a draw string connected with the said bottom ring approximately at diametrically opposite points on the ring, the said draw string extending upwardly along the curtain at the outside to and over the head, said head having openings extending therethrough, and the said draw string passing through the said openings and extending downwardly within the curtain to a position to be grasped for collapsing the curtain, the said draw string having frictional engagement with the said head to sustain the shade in collapsed form.

2, A lamp shade including a curtain flaring in a downward direction, means to secure the upper end of the curtain to a lamp, annular bands of stiff material on said ourtain of gradually increasing size toward the lower end of the curtain, and a draw string connected with the said curtain at the lower end thereof at opposite sides, said draw string extending over the first-mentioned means at the upper end of the curtain and then downwardly in looped form within the shade to a, position to be grasped.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ROBERT L. CLARK.
